DRIVING MECHANISM FOR WINDING-MACHINES.

Specification of Letters Patent.

Patented July 8, 1913.

Application filed May 21, 1912. Serial No. 698,767.

To all whom it may concern.

Be it known that I, GRANT Sirr, a citizen of the United States, residing at Paterson, in the county of Passaio and State of New Jersey, have invented certain new and useful Improvements in Driving lVlechauisms for W'inding-Vlachines, of which the following is a specification.

This invention relates to winding and similar machines and it has reference particularly to the means for transn'iitting rotation from the driving pulley or the like in such machines to the rotary shaft or shafts by which the spools or bobbins are driven.

The principal object of the invention is to provide means whereby the speed of rotation of the shaft or shafts (or their equivalent) above referred to may be changed at will by the operator and whereby said shaft or shafts may be started or stopped gradually and smoothly, thus avoiding undue strain on the threads on the one hand or undue relaxation thereon the other.

The invention consists in the improved mechanism for accomplishing the foregoing and other objects to be indicated hereinafter set forth in the clauses of the claim and exemplified here in its preferred form.

In the accompanying drawings, Figure 1 shows the improved mechanism in side elevation, partly in section; Fig. 2 is a view showing approximately one-half of the mechanism in plan and the other half in section substantially in the horizontal plane of the axes of the shafts carrying the faceplaces; Fig. 3 is a vertical sectional view of the mechanism in the vertical plane of the right-hand one of said shafts in Figs. 1. and 2, the shifter for the friction-wheel and certain other parts appearing in elevation; and, Figs. 4: and illustrate details.

The frame structure shown in the drawings comprises the lower part a, tapering upwardly as indicated by the dotted line a in Fig. 1, and the upper part b which rests on a ledge c of the part a and is bolted flat wise against the upwardly tapering portion of the latter at the three points (Z. It will be understood that the structure thus described is one of two or more similar structures of the winding or other machine, the same being rigidly connected together by the tie-rods e.

The part b of the frame structure is cast with two laterally disposed housings f each vertically elongated and open at the back in Fig. l (or inner side, in Figs. 9. and 5)) and provided with a cover-plate suitably secured to the part 7) by the screws l1.

I'lach spool or l)()l)l)ll1 A has its whirl A resting in the usual manner on the periphery of one of the drive-wheels 2 which are carried by the upper and lower shafts j (there being one pair of such shafts to each housing), the ends of which shown in the drawings are fitted into and clutched to the hubs of gears 7.: (inclosed in the housings) each having a short shaft Zfixedly secured therein and journaled in the outer or front wall of the housing 7, cover-plate 9 being apertured to admit each hub; it will be understood that the parts j, 7; and Z rotate substantially as one member and that they are formed as separate parts for convenience in assembling.

Each cover-plate g has an inwardly projecting attenuated socket m disposed mid way between, parallel with and in the same vertical plane (preferably) with the shafts j, which socket and a bearing a in the outer wall of the housing afford journals for a shaft 0 having, secured upon it, a pinion 7) in mesh with the gears and, mounted in its inner end, a thrust pin 1 which bears against a ball 7' seated on the head of a pin 8 between which and the inner end of the socket a spiral spring 6 is interposed. Keyed to each shaft 0 on its outer or exposed end is a face-plate a; the working or outer faces of the two face-plates stand in substantially the same vertical plane.

At the points o there is attached to the frame, by screws (Figs. 1 and 2), a housing '11) which is open at the bottom and has its end-walls 10 extended dowmvardly and supporting the horizontal parallel guide-rods m. In bearings y, secured in the two outer end walls of said housings by the screws .2, is journaled the shaft 2 carrying the pulley 3 whereby power, through the medium of an endless belt (not shown), is taken into the machine, endwise movement of said shaft be-' 'ing prevented by the collars a abutting the inner sides of said bearings. On this shaft, within each housing, issplincd a frictionwheel 5 having its periphery bearing against the face of the corresponding face-plate, the periphery of said friction wheel being leather or other suitable material which will effectively grip the face of the face-plate. The hub of each friction-wheel has a peripheral. groove 6 which receives the arm 7 of a shifter 8 which is arranged to slide on the guide-rods w.

Each shifter has a depending portion forming a nut 9 in which is received the threaded inner end of an adjusting screw 10 having a hand-wheel 11 at its outer end and journaled horizontally, parallel with the guide rods, in a bearing bracket 12 in which are the set-screws 13 which bear against the outer depending portions of the end-walls w of the housing, exerting binding action on the guide-rods calculated to hold both them from endwise movement in the housing and the bracket from similar movement on the guide-rods. Endwise movement of the screw 10 is prevented by its hand-wheel and the washer 14 (abutting the pin 15) which bear against opposite sides of said bracket.

In view of the foregoing, it will be apparent that, with shaft 2 rotating and the friction-wheels in contact with the faceplates, rotary motion will be transmit-ted to the spools A from the face-plates through the parts 0, p, 70, Z, j and 2'. It will be furt-her apparent that the speed at which the spools are driven may be varied'hy adjusting the shifters to change the positions of the frictionqvheels relatively to the faceplates, and that the adjustment of the driving mechanism for either set of spools is entirely independent of that for the other.

The highest speed obtained from either friction-wheel of course corresponds to that position of the friction-wheel where it stands near the center of the face-plate: when the friction-wheel is shifted toward the margin of the face-plate the speed obtained gradually reduces. According to this invention I provide for having the frictionwheel and face-plate engage and disengage each other, respectively, to start and arrest the face-plate and the parts driven therefrom, when the friction-wheel stands, relatively to the face-plate, in theposition (just indicated) where the speed transmitted is the lowest speed, preferably accomplishing the engagement and disengagement of these parts as follows: In the outer face of the face-plate is fitted, axially thereof, a bearing-pin 16 having a rounded head and capable of free rotation in the face-plate. When the friction-wheel stands in the position of lowest transmitted speed this pin bears against a roller 17 journaled, with its axis vertical, in a socket or bearing formed at the upper end of anarm 18 projecting upwardly from the shifter, said socket being cut away at 19 to allow the pin to engage the roller. In this position of the part-s, the face-plate is crowded inwardly (spring 2? allowing it to yield) out of contact with ,the frictionwheel, so that it is uninfiuenced thereby. Upon adjusting the shifter, and consequently the friction-wheel inwardly, however, as soon as the pin clears the roller, en gagement of the friction-wheel with the face-plate is established so that the latter will be driven. Once such engagement is established the transmitted speed will increase as the adjustment of the friction-wheel inwardly continues. To prevent the frictionwheel from assuming a position directly alined with the axis of the face-plate, where it would no longer drive the latter, the sleeve-extension 20 of the shifter is adapted to abut the outer side wall of the housing. To limit the movement of the friction-wheel past the point where the pin 16 bears upon the roller 17 the arm 18 has a stop 21 to engage the side of said pin.

The bearing-pin serves, of course, as an anti-friction bearing. It is found, however, that if it is allowed (when not engaged with the roller 17 to rotate with the face-plate it is likely, upon impact with the roller, to continue such rotation, thereby wearing an undesirable dent or hollow in the cylindrical face of the roller. To keep it therefore against rotation with the face-plate the breaking-pin carries a wire or the like which hangs pendant as shown in Figs. 3 and 5 and engages in a slot 22 formed in the shifter.

On the outer face of each housing is marked a scale 23 with reference to which pointer 24: on the corresponding shifter is movable, means being thus afforded for inj dicating the speed of rotation of the spools.

25 is a trough which is suspended from the guide-rods and serves to catch any oil dripping from the superjacent mechanism.

It will be apparent that it is not essential to the operation of separating the friction wheel and face-plate that the pin 16 be revo-luble in the face-plate. The functionto be performed is the camming or crowding of the face-plate and friction-wheel apart, requiring a cam-surface to be provided on either the projection afforded by said pin, as by rounding it, or on the shifter, as the rounded surface of its roller 17, or on both, as here illustrated.

Having thus fully described my invention, what I claim as new and desire to se cure by Letters Patent is:
